datum momentum_compaction_ptc.N not updating when K2 are changed

[MichaelEhrlichman]

The higher order momentum compaction should be changing when a K2 in a dispersive region is adjusted. However, momentum_compaction_ptc.N remain uneffected when K2 vars are adjusted.

Test case at lns in /home/ehrlichm/for_dcs/99

tao
sho data ac
cha var all_k2 @0
sho data ac

@MichaelEhrlichman Is it possible for you to come up with a simpler example that takes less time? Thanks.

@DavidSagan /home/ehrlichm/for_dcs/99 should be much faster now.

@MichaelEhrlichman Problem is that the data does not show a dependency on k2. So if you start Tao with a lattice with k2 zero you get the same data as with a lattice with finite k2. If Tao is started with RF off (--rf command line switch) the problem goes away. I will work on this further but for now you have a work around.
